Yemeni Houthi rebels claimed Monday that Saudi fighter jets were using phosphorus bombs in raids against the rebels' positions along the border, al-Jazeera news channel reported.
The Saudi combat fighters launched intense raids against areas inside Yemeni territories on Sunday night, the rebel group spokesman Mohamed Abdul Salam was quoted by the Doha-based channel as saying, Xinhua reported.
He said the warplanes used "white phosphorous bombs" in their attacks, which targeted the rebels' positions in Yemen's al- Malahit area, seven kilometers away from the border.
The allegation could not be independently verified at present.
Abdul Salam also denied allegations by the Saudi side of having regained control over the border territory of Jabal al-Dukhan, which had been seized by the Shiite rebels in a cross-border attack a few days ago, saying the rebels "are still present in the area."
Meanwhile, Yemen-based News Yemen website reported that fighting between Saudi troops and the Shiite rebels continued along the border on Sunday night.
The clashes erupted again following an announcement by Saudi Arabia that it recaptured Jabal al-Dukhan, local sources told the Yemeni news net.
The Houthi rebels fired mortar shells throughout the night from the border area of Jabal Twiliq at Saudi villages, while Saudi forces launched air raids and artillery attacks on the borderline, the report said.
No information on casualties was available until now.
